Car Tire Valve Cap, 12PCS Blue Fluorescence, Bike Motorcycle Noctilucous Illuminated Universal Wheel Caps for Truck Motorcycles Tires, Need Sunlight to Absorb Energy
【DOUBLE PROTECTION】- The fluorescent car tire valve caps feature illuminated plastic inserts and clear housing protection to prevent valve stem corrosion.
Our tire valves caps inside with the Rubber Seals, create a tighter, more effective seal, so there’s no air leaking on long, tough drives.
【FLUORESCENT EFFECT】- The inner layer of the valve stem cover is designed with luminous material, which can make the car decorated with Tire Valve Stem Caps lights at night.
When your wheel starts to move, it automatically flashes and creates a circle of light that makes your car/motorcycle/bike look beautiful.
【NOTE】- Since the fluorescent material needs to absorb the light source, it glows at night. Stem caps do not absorb light sources when stored in airtight packaging for extended periods of time.
Illuminate with LEDs or place them in sunlight for 4-6 hours before using fluorescent stem caps for the first time.
【EASY INSTALLATION】- Easy installation without tools. Simply screw it onto the tire valve stem. It's easy to install or remove when you want to check air pressure.
【WIDELY USED】- The inner diameter of tire valve caps is 8mm, fits most cars, buses, SUVs, trucks, motorcycles, bicycles, etc., keeping the tires of vehicles at the proper inflating level.
【Note】: The product material is ABS leather + phosphor powder, which belongs to the storage light material. It absorbs light when there is light and emits light when it is dark.
However, the exposure to the sun during production and transportation is short. If it does not emit light after purchase, please put the item in the sun.
【Scientific explanation】: Photo-induced energy storage luminous powder is a fluorescent powder that stores light energy after being irradiated by natural light, fluorescent light, ultraviolet light, etc.,
and then slowly releases it in the form of fluorescence after the light irradiation is stopped. Therefore, at night or in the dark, one can still see the glow, lasting as long as several hours to ten hours.
